Question

The latent heat of fusion of ice is 3.4 X 105 J/Kg. What do you mean by this statement? Explain

Answer 1

The given statement means that 3.4 X 10⁵ J of additional heat is required per kilogram to convert solid ice at 0°C into liquid water at 0°C.

- The latent heat of fusion implies the heat required for phase change between states of solid and liquid.

- So in other words,the given statement means that 3.4 X 10⁵ J is the amount of heat needed to change the mass of 1 kg ice from solid state at its melting point into liquid form at the same temperature.
